Barium selenite

Barium selenite (CAS 13718-59-7), with the formula BaSeO3, is an inorganic barium salt of selenious acid used in specialty electronics and materials manufacturing. It serves as a controlled source of both barium and selenium in high-purity synthesis and ceramic processing applications.

In electronics, this compound functions as a precursor in the production of selenium-containing compounds and doped ceramic materials where precise elemental ratios are required. It is used in the manufacture of specialty glass formulations, including optical and radiation-shielding glass.

Selenium contributes specific optical properties that influence light transmission characteristics in these glass types. Research and industrial synthesis operations use it as a starting material for preparing other barium or selenium compounds under controlled conditions.

Ceramic and phosphor material producers may incorporate it into formulations requiring a stable, low-solubility selenium source. This material is supplied as a white to off-white crystalline powder for various industrial applications.

It is available primarily in technical and research grades, with purity levels typically specified by suppliers for laboratory and industrial use. Packaging is generally offered in small to medium quantities given the specialized nature of demand.

The product meets rigorous internal specifications for consistency and performance in high-tech manufacturing environments. Suppliers ensure that the chemical properties align with the requirements of advanced material science and electronic component production.
